There are several tools and controls to construct logarithmic to linear workflows depending on your needs.
Since Composite processes are optimized for linear data, when you import an image, the Import Options are in their Active state, and logarithmic data (Cineon, DPX) is automatically converted to linear data. If you need to export into Cineon or DPX format, the data is transformed back to logarithmic.
In the Active state, you can make adjustments to both the film gamma and to the reference white of the image you are importing or exporting.
You can, however, override these settings by changing the default Active setting on import (and export) to Inactive. You can then make modifications to the image using the 1D and 3D LUT tools, as well as the Log and Delog tools.
